- mineral finishing, levelling and self-levelling products with normal, rapid and extra-rapid setting
Substrates:
- flooring in ceramic, marble-floor tiles and natural stone
- flooring in concrete smoothed with circular grinding machinery
- compact and smooth cement-based screeds
- prefabricated concrete and fresh concrete castings
- wooden panelings
- hardwood floors
- substrates in metal on rigid supporting surfaces
- flooring with residual traces of resin-base adhesives
- flooring in epoxy resin
- varnishes
- rigid PVC coatings
- flooring grade bitumen/asphalt
- Class 3 plywood
Field of application Directive CE ME
Adhesion promoter primer for cementitious substrates.
Mass per area 140 ± 5% (g/m2 ).
As primary decks coverings. The product may be applied to any metallic support having a thickness ≥ 2.25 mm.
Do not use
On highly flexible substrates or substrates which may present a risk of strong dimensional movement; on substrates which are moistened or subjected to moisture rising, for overlaying of mortars and plasters with semi-dry consistency and high granulometric grading.
Kerakoll Keragrip Eco – Instruction For Use
Preparation of substrates
Substrates must comply with BS 5385, parts 1-5, be stable and non-deformable, without cracks and have already completed the curing period for hygrometric shrinkage; must be free from dust, oil and grease, free from any rising damp, with no loose, flaky material Surface treatments of certain materials such as waxes for resilient materials, marble floor tiles, hardwood floors, concrete parting compounds and sheet-metal oils must be completely removed. Varnishes, wall paints and adhesives that are not perfectly anchored must be removed mechanically.
Absorbent substrates must be compact.
Instruction for use
On non-absorbent substrates and timber substrates: shake the can well before opening. Kerakoll Keragrip Eco is immediately ready for use. Pour Keragrip Eco from the can onto the substrate to be covered. Apply a fine, uniform film, preferably using a sponge or synthetic fibre roller and working in the same direction. Apply a second pass criss-crossing the direction of the first to ensure full coverage of the substrate. The colouring allows the user to check whether the application is complete and uniform. Avoid any build-up of product.
Once hardened, Keragrip Eco will withstand light foot traffic. Any traces of dirt must be removed using a suitable vacuum cleaner.
Tools
Synthetic or sponge rollers or brushes. Wash tools with water before the product hardens.
Special Notes
The maximum period allowed for overlaying is 24 hours.Once this period has elapsed, a new, complete application of Kerakoll Keragrip Eco will have to be carried out directly over the existing application.
Direct bonding with cement-based adhesives must be carried out by applying a fine levelling layer of adhesive with the smooth part of the notched trowel, so as to ensure total contact with the adhesion promoter.
